Argentina’s telecommunications sector is undergoing a period of technological and structural change. Initially, the country reached a milestone of 2,300 active 5G sites, accounting for 10% of the national mobile infrastructure. This expansion occurred alongside rising connectivity demands, with internet access exceeding 51 million users in early 2026.

As the sector evolves, the market is seeing significant shifts in competition and scale. Mobile accesses have reached 64.55 million, resulting in a penetration rate of 139.05 accesses per 100 inhabitants. A major driver of this structural transformation is the conditional authorization of Telecom’s acquisition of Telefónica Móviles Argentina. To preserve market competition, regulators have required the transfer of six million mobile customers and related infrastructure to a new competitor, as well as the return of radio spectrum.
